Dispensing device



June 26, 1934. Rl R CCNE DISPENSING DEVICE Filed Sept. l5. 1953 gjm/vento@ avh ji. Cane Patented June 26, 1934 A.UNITED STATES PATENT OFFICE The present invention relates to a `device for dispensing liquids, particularly where it is desired to raise the liquid in a container of the type employed for inks, medicines, etc.

Whereas there are numerous prior disclosures not susceptible to use with containers already on the market. Other devices have been proposed in which a separate level raising well is inserted into'the mouth of its container, but these wells have slots provided in their side walls, rendering it impossible to bring the liquid close to the top of the container and thus, by their design, defeat.,

the primary `purpose for which they were intended.

The desirability of an efficient device for raising the level of ink in a bottle, for example, is evidenced by these unsuccessful attempts in the pastto provide'an arrangement whereby a pen might be dipped into or'flled from the original container without soiling the portion ofthe pen which is grasped when in use for writing. It is the object of the present invention to overcome these faults and diiculties which are prevalent in the prior art and fulfill the requirements of the trade with a device which is simple and compact, inexpensive to manufacture and`convenient to operate. The invention distinguishes, for exexample, over patents such as those to Gosselin No. 1,273,479 dated July 23, 1918 and Hauser No. 1,896,405 dated February '7, 1933. The present invention is applicable to existing containers and contemplates an auxiliary container or liquid level raising well which frictionally engages the internal wall of the principal Fig. 2 is a perspective of a form of the auxiliary container;v

Fig. 3 is a plan of the auxiliary container;

Fig. 4 is a section through 4-4 of Fig. 2; and` Fig. 5 is a modification. f f 60 Referring to the drawing in detail, 10 represents an ink bottle ofthe usual type having a vreduced neck 11r and an inner wall 12. A closure 13, provided with fastening means such as screw threads 14, engages with cooperating means such as screw threads 15 provided on the neck of the bottle. For the reception of ink when the bottle is inverted, the closure is provided witha chamber 16. A ange 17 may be formed internally of the closure for reception of a gasket 18 of any 70 suitable material for binding engagement with the rim 19 of the bottle.

Received within the neck of the bottle is an auxiliary container or level raising well 20 whose inner and outer walls 21 and 22 respectively are preferably tapered to the same degree, forming in effect a frustroconical member closed at its smaller base. `The outer wall 22 is provided with a flanged portion 23 which may have a rounded. lower edge,`Fig. 2, or a more abrupt shoulder, Fig. 5, which anged portion is continued to the larger base of the `frustro-conical member to constitute a rim 24. The ange 23 is provided with cut-out portions 25 which may conveniently assume the form of iiuting. 85 As shown in Figs. 1 to 4, the outer periphery 26 of the flange 23 is-substantially cylindrical while in the modification in Fig. 5 it is designated as 26 and shown as slightly tapering or frustroconical. In this mannery when the well is applied .90 to.an existing container or bottle whose inner wall is tapered` o r provided with a bulge, the form in Fig. 1 might be conveniently employed, while in a container or bottle having a cylindrical bore theformin Fig. 5 would be preferred. 95

Due to the fluting` provided in the ange, the rim of the well will present a thin surface of material making the well susceptible to flexibility in the neighborhood of the rim so that a forced lit in the bottle may readily be achieved.

It is clear that during manufacture of the auxiliary containersthey may be nested together for operating upon several of them at thesametime. This possibility 0f nesting maynd additionalr importance for purposes of storage and shipping.

A variety of materials may be employed for fabricating the auxiliary container among which might be mentioned wood, cork, paper, rubber, metal, Celluloid, cellophane, pressed compositions or compositions impervious to the chemicals present in the liquid to be dispensed. It is also contemplated to make the flange portion a separate member under which conditions the auxiliary container may be composite and constructed of different materials. In a like manner the closure element may be made of a variety of materials and may also be composite.

In operation, assuming a liquid level in the bottle at the height indicated at 27, the bottle is slowly inverted so that the liquid passes between the outer wall 22 of the auxiliary container and the inner wall 12 of the principal container through the passages or utes 25 into the chamber 16 provided in the closure element. The bottle is then quickly righted to assume its normal position whereupon theliqui'd will pass from the chamber into the auxiliary container, establishing a liquid level therein which is only slightly below the rim of the bottle. This distance is only sufficient to prevent an overflow of liquid from the bottle itself. It will be obvious that the chamber in the closure must have a content equal to or greater than the content of the well in order to assure complete filling of the latter.

It is contemplated that suitable uting might be formed in the container itself, in which event the well or its ange need not be fluted. It is also'intended that the invention be adapted to containers of any sectional form, with or Without reduced portions, and that the section of the well be made in any efficient form and not necessarily frustro-conical.

This invention is not to be restricted to shapes or materials except as specified in the appended claims.

A dispensing device comprising a container having a rim and an opening, an auxiliary container having a rim and having a discontinuous flange in positive engagement with the inner wall of the first named container, said rims dening a volume therebetween less than that of the auxiliary container and a chambered closure for said containers which defines withthe rim of the auxiliary container, a volume as great as the capacity of said auxiliary container.

2. A dispensing device comprising a container havingan opening, an insertable `auxiliary container disposed within and in positive wedged engagement with, the inner wall of the first said container, a passage between the inner wall of the first said container and said auxiliary container, and a chamberedclosure for said containers having a capacity substantially equal to that of said-\ auxiliary container.`
